Increase your home backup capacity with the MyGrid 10K Solar Battery, designed specifically for seamless integration with the MyGrid 10K whole-home generator system. Whether you're preparing for longer power outages, increasing your available solar energy storage, or building a more capable off-grid power system, this expansion battery gives you the flexibility to grow your energy storage as your needs change.
The MyGrid 10K system supports up to six expansion batteries, allowing you to increase total system storage capacity to as much as 73,742Wh. This scalable design makes it possible to start with the capacity you need today and expand your battery storage later.
Additional stored energy can provide longer backup runtime during extended outages and greater flexibility when using solar power or operating in off-grid applications.
Designed with installation flexibility in mind, MyGrid 10K batteries can be stacked up to three batteries in a single row. This helps create a clean, organized installation while making better use of available space in garages, basements, utility rooms, and dedicated power-storage areas.
The MyGrid 10K Solar Battery uses lithium iron phosphate (LiFePO4) battery chemistry, providing dependable energy storage, thermal stability, consistent performance, and long service life.
An integrated Battery Management System (BMS) monitors and manages battery operation to support safe charging, reliable performance, and battery longevity. An easy-to-read LED display provides convenient access to battery status information.
Expanding your MyGrid 10K system doesn't require complicated connections. Expansion cables are included, providing an easy connection between compatible batteries and helping simplify installation.
